Taylor Swift's '1989' Set for Sixth Week at No. 1 on Billboard 200

Nicki Minaj and D’Angelo on course for top 10 debuts.

Taylor Swift's 1989 is heading back to No. 1 on the Billboard 200 chart.

Industry forecasters suggest the album may sell over 340,000 copies in the week ending Dec. 21, while its overall album consumption figure could approach 390,000.

The recently revamped Billboard 200 chart now ranks albums based on their overall consumption. That overall figure combines pure album sales, along with track equivalent albums (TEA) and streaming equivalent albums (SEA).

The new Billboard 200's top 10 will be revealed on Wednesday, Dec. 24.

If 1989 returns to No. 1, it will mark the 30th cumulative week atop the Billboard 200 chart for Swift. She previously reigned with Fearless (11 weeks in 2008 and 2009), Speak Now (six weeks in 2010 and 2011) and Red (seven weeks in 2012 and 2013).

Two new albums are on course for top 10 debuts on the new chart: Nicki Minaj's The Pinkprint and D’Angelo and the Vanguard's surprise album release Black Messiah.

Minaj's album may sell around 160,000 copies, while D'Angelo's set could shift 100,000.
